Single word for "break" with professional connotation

What is a nice way to explain that performing a certain action will "break" a product? I have to explain to a customer that use of my product in an unauthorized manner will "break" the product, but I'd like to use a word that has the same meaning but more professional connotation while maintaining the robustness/integrity of my product in their eyes.

For a physical object, "damage" is the usual choice in my experience. For software, you sometimes see "corrupt", though that usually applies to data and not the product itself.

How about compromise?

To reduce in quality, value, or degree; weaken or lower.

I think this word has the advantage of implying any damage done would be due to user-error rather than a lack of "robustness" of the product.

I think they usually say:

Usage of the product in an unauthorized manner may damage the product.
